Cette technique est très intéressante car permettant une réutilisation de produits généralement traités comme des déchets et un abaissement du prix de revient des liants fibreux servant de base à la fabrication de revêtements décoratifs.This technique is very interesting because it allows the re-use of products generally treated as waste and a lowering of the cost price of the fibrous binders used as a basis for the manufacture of decorative coatings.
Selon la teneur en fibres des boues papetières, les fibres ajoutées sont des fibres de cellulose de plus grande longueur que celles présentes dans les boues, des fibres synthétiques telles que fibres de polyoléfine telle que polyéthylène, polypropylène ou de polyamide; des fibres minérales (laine de roche) celles-ci pouvant être incorporées en toutes proportions, selon l'utilisation finale du liant fibreux.Depending on the fiber content of the paper sludge, the fibers added are cellulose fibers of greater length than those present in the sludge, synthetic fibers such as polyolefin fibers such as polyethylene, polypropylene or polyamide; mineral fibers (rock wool), which can be incorporated in any proportion, depending on the end use of the fibrous binder.
Les polymères filmogènes sont des polymères naturels et/ou synthétiques, solubles, émulsionnables ou dispersibles dans l'eau. Il peut s'agir de polymères dérivés de la cellulose, non-ioniques ou anioniques, de dispersion de composés de types vinyliques et/ou acryliques et leurs dérivés en milieu aqueux, des alcools polyvinyliques, des polymères dérivés de la cellulose, ou d'une combinaison de ces polymères.Film-forming polymers are natural and / or synthetic polymers, soluble, emulsifiable or dispersible in water. They may be polymers derived from cellulose, nonionic or anionic, dispersion of compounds of vinyl and / or acrylic types and their derivatives in an aqueous medium, polyvinyl alcohols, polymers derived from cellulose, or a combination of these polymers.
La composition selon l'invention peut également, selon sa destination, contenir des fibres de laine de roche, de la farine de bois, de la perlite, de la vermiculite, des micro-ballons de verre ou des agents ignifugeants lui conférant des qualités particulières.The composition according to the invention can also, depending on its destination, contain rock wool fibers, wood flour, perlite, vermiculite, glass micro-balloons or flame retardants giving it particular qualities. .

Conformément à un mode de réalisation de cette composition, un agent moussant lui est ajouté afin de provoquer la formation de bulles d'air lors de la projection du produit sous pression. L'allégement ainsi obtenu pour le produit améliore les qualités thermiques et acoustiques du revêtement.In accordance with one embodiment of this composition, a foaming agent is added thereto in order to cause the formation of air bubbles during the projection of the product under pressure. The reduction thus obtained for the product improves the thermal and acoustic qualities of the coating.
Conformément à une variante, l'agent moussant est incorporé au moment de la dilution de la pâte, juste avant application de celle-ci.According to a variant, the foaming agent is incorporated at the time of the dilution of the paste, just before application thereof.
Un procédé d'obtention de cette composition consiste à partir de boues papetières avant concentration et dessication partielle lorsqu'elles sont pompables et contiennent de 5 à 20 % de matières sèches, et à disperser dans cette suspension les fibres et polymères solubles et/ou dispersibles apportés en complément, avant de réaliser une agitation pendant 30 minutes environ permettant l'obtention d'une pâte lisse et homogène qui constitue le liant fibreux.A process for obtaining this composition consists of paper sludge before concentration and partial desiccation when they are pumpable and contain 5 to 20% of dry matter, and in dispersing in this suspension the soluble and / or dispersible fibers and polymers added as a supplement, before stirring for approximately 30 minutes, making it possible to obtain a smooth and homogeneous paste which constitutes the fibrous binder.
Un autre procédé de préparation de la composition selon l'invention consiste à partir d'un extrait de boues papetières contenant environ 50 % de matières sèches, à disperser cet extrait dans l'eau sous forte agitation, puis à ajouter à cette dispersion les fibres apportées en complément et les polymères solubles et/ou dispersibles avant d'obtenir une pâte lisse et homogène après une période d'agitation de 30 minutes environ.Another process for preparing the composition according to the invention consists in dispersing this extract from paper sludge containing approximately 50% of dry matter, in dispersing this extract in water with vigorous stirring, then in adding to this dispersion the fibers. supplemented with soluble and / or dispersible polymers before obtaining a smooth and homogeneous paste after a stirring period of approximately 30 minutes.

Cette composition présente l'avantage de pouvoir être enlevée, par simple imprégnation à l'eau chaude ou à la vapeur, si le polymère utilisé est un dérivé de la cellulose ou est essentiellement constitué d'un dérivé de la cellulose.This composition has the advantage of being able to be removed, by simple impregnation with hot water or steam, if the polymer used is a derivative of cellulose or essentially consists of a derivative of cellulose.
Les exemples ci-après décrivent, à titre non limitatifs, plusieurs possibilités de réalisation de compositions selon l'invention:The examples below describe, without limitation, several possibilities for producing compositions according to the invention:
On introduit dans une cuve les boues, les fibres, le bactéricide, sous agitation, on ajoute la méthylcellulose. Après 30 minutes, on obtient une pâte lisse et homogène, à laquelle on ajoute sous agitation modérée le complément d'eau. La composition fibreuse est prête à l'utilisation.Sludge, fibers, bactericide are introduced into a tank, with stirring, methylcellulose is added. After 30 minutes, a smooth and homogeneous paste is obtained, to which the additional water is added with moderate stirring. The fibrous composition is ready for use.
Les produits sont mélangés de façon homogène au liant fibreux jusqu'à obtention d'une pâte consistante. Le produit peut être dilué avant application, et donne un crépi rustique intérieur. Ce revêtement peut être coloré dans la masse à l'aide d'oxydes de fer et/ou de pigments organiques.The products are mixed homogeneously with the fibrous binder until a consistent paste is obtained. The product can be diluted before application, and gives an interior rustic plaster. This coating can be colored in the mass using iron oxides and / or organic pigments.
On obtient par incorporation des éléments ci-dessus, au liant fibreux, un revêtement décoratif ayant des qualités de récupération acoustique intéressantes.Obtained by incorporating the above elements, with the fibrous binder, a decorative coating having advantageous acoustic recovery qualities.
En incorporant les éléments ci-dessus, au liant fibreux, on obtient un revêtement qui peut être appliqué en forte épaisseur (30 millimètres) et possède des caractéristiques acoustiques intéressantes, du fait du "gonflant" apporté par la fibre de polypropylène et de l'inclusion de bulles d'air dues au lauryléthersulfate lors de la projection de la pâte.By incorporating the above elements, with the fibrous binder, a coating is obtained which can be applied in very thick (30 millimeters) and has interesting acoustic characteristics, due to the "swelling" provided by the polypropylene fiber and the inclusion of air bubbles due to laurylethersulfate during the projection of the dough.
On obtient en mélangeant les produits ci-dessus au liant fibreux de l'Exemple 1, un revêtement possédant d'excellentes qualités d'accrochage sur tout support et ayant un effet décoratif du fait de la présence de grains grossiers dans le film.Is obtained by mixing the above products with the fibrous binder of Example 1, a coating having excellent bonding qualities on any support and having a decorative effect due to the presence of coarse grains in the film.
Par incorporation d'un agent insecticide rémanent non soluble en milieu aqueux, on obtient un revêtement intérieur décoratif présentant des qualités insecticides contre les insectes volants (mouches, moustiques) et rampants (araignées).By incorporating a non-soluble residual insecticide agent in an aqueous medium, a decorative interior coating is obtained having insecticidal qualities against flying (flies, mosquitoes) and crawling (spiders) insects.
De la même façon, on peut introduire dans la formule de l'Exemple 4, un ou plusieurs agents ignifugeants, (substances halogénées ou phosphorées, oxyde d'antimoine, dérivés de l'acide borique) qui confèrent au revêtement épais des qualités de retardateur à la propagation du feu intéressantes.In the same way, one can introduce into the formula of Example 4, one or more flame retardants, (halogenated or phosphorous substances, antimony oxide, derivatives of boric acid) which give the thick coating retardant qualities. to the spread of interesting fire.
Comme il ressort de ce qui précède, l'invention apporte une grande amélioration à la technique existante en fournissant une composition très performante, et d'un prix de revient modéré compte tenu de la mise en oeuvre dans des proportions importantes de produits (de 20 à 80 % de la masse totale), considérés et traités jusqu'alors comme des déchets.As is apparent from the above, the invention brings a great improvement to the existing technique by providing a very effective composition, and a moderate cost price taking into account the use in significant proportions of products (from 20 at 80% of the total mass), considered and treated until then as waste.
